Re: Assigning a timestamp without timezone to a timestamp

Thanks Tom that's great!!

When I first saw your solution I thought it was logically going to do
(notice the parentheses):
select ('2006-07-13 09:20:00'::timestamp) at time zone 'EST5EDT';
which does not help

So I was not hopeful, but when I tried it it did exactly what I needed which
is:
select '2006-07-13 09:20:00'::(timestamp at time zone 'EST5EDT');

My adjusted SQL is:

select start_datetime
, cast(start_datetime as timestamp(0) without time zone)::timestamp at
time zone B.timezone_ch
from reservation A
, location B
where A.appt_key = 7
and B.locn_key = 102;

thank-you so much
